abstract = {Increasing the growth rate of the industrial host
Corynebacterium glutamicum is a promising target to rise
productivities of growth coupled product formation. As a
prerequisite, detailed knowledge about the tight regulation
network is necessary for identifying promising metabolic
engineering goals. Here, we present comprehensive metabolic
and transcriptional analysis of C. glutamicum ATCC 13032
growing under glucose limited chemostat conditions with μ =
0.2, 0.3, and 0.4 h–1. Intermediates of central metabolism
mostly showed rising pool sizes with increasing growth.
13C-metabolic flux analysis (13C-MFA) underlined the
fundamental role of central metabolism for the supply of
precursors, redox, and energy equivalents. Global,
growth-associated, concerted transcriptional patterns were
not detected giving rise to the conclusion that glycolysis,
pentose-phosphate pathway, and citric acid cycle are
predominately metabolically controlled under
glucose-limiting chemostat conditions. However, evidence is
found that transcriptional regulation takes control over
glycolysis once glucose-rich growth conditions are
installed.},
